Problem on mile markers

Hi,

Can anyone clarify how mile markers are used? Is it that as you progress to the right the mile marker shows smaller numbers?

Have attached the problem in the image.


Thanks,

Hi mallika hunsur,

Yes - when you move 'to the right' in this question, the mile markers will decrease. To properly answer this question, you have to note the units involved (in this case, we're dealing with TENTHS of a mile). Here's how you can solve it step-by-step:

1) Draw a line and place a marker (marker 4.6) on the line.
2) Marker 4.6 is 2/5 of a mile west of Jake's house. 2/5 = .4, so place a marker for Jake's house at marker 4.2 (this marker is to the RIGHT of marker 4.6)
3) Place marker 5.2 on the line (this marker is to the LEFT of marker 4.6).
4) Marker 5.2 is 3/5 of a mile west of Quincy's house. 3/5 = .6, so place a marker for Quincy's house at marker 4.6.

You can now solve for the distance between Jake's house and Quincy's house: 4.6 - 4.2 = .4 miles

Final Answer: B

"runs east to west" is the key: we'd expect the mile markers to begin in the east (with mile marker 0 or mile marker 1), then rise as we head westward (to mile markers 2, 3, 4, ...)
